ASE A4 practice test questions with correct
answers
2. A driver says that the front end of his car vibrates up and down while
|| || || || || || || || || || || || || || || ||
traveling at most road speeds. Tech A says that too much runout of the
|| || || || || || || || || || || || || ||
front wheels could be the cause. Tech B says that a static out of balance of
|| || || || || || || || || || || || || || || ||
the front wheels could be the cause. Who is right?
|| || || || || || || || ||
A. Tech A only
|| || ||
B. Tech B only
|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-C. Both Techs are right. Too much
|| || || || || || || || || || || || ||
runout or static out of balance in the front wheels will cause a vibration
|| || || || || || || || || || || || || ||
3. A vehicle has front wheel shimmy at low speed and requires increased
|| || || || || || || || || || || || ||
steering effort. Tech A says that too much positive camber could be the
|| || || || || || || || || || || || ||
cause. Tech B says that too much Positive caster could be the cause. Who is
|| || || || || || || || || || || || || || ||
right?
A Tech A only
|| || ||
B. Tech B only
|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-B. Excessive positive caster will
|| || || || || || || || || || || ||
increase steering effort, cause the steering wheel to return too rapidly. cause
|| || || || || || || || || || ||
wander at high speed and shimmy at low speed.
|| || || || || || || || ||
,4. All of these could cause tire wear if not within manufacturer's Specs
|| || || || || || || || || || || || ||
EXCEPT:
A. Caster
||
B. Wheel balance
|| ||
C. Toe-In
||
D. Camber - CORRECT ANSWER✔✔-A. Caster that is out of spec will affect
|| || || || || || || || || || || || ||
steering and handling characteristics, but will not cause tire wear. Whereas,
|| || || || || || || || || || ||
too much toe in or out would severely wear the tires. Additionally, excessive
|| || || || || || || || || || || ||
camber would cause inside or outside shoulder wear on the tire, depending
|| || || || || || || || || || || || ||
on whether the camber was too negative or positive.
|| || || || || || || ||
5. A vehicle with variable assist power steering has a lack of power assist in
|| || || || || || || || || || || || || || ||
both directions. Tech A says That the problem is in the electronic control
|| || || || || || || || || || || || ||
system. Tech B says that there could be a problem in the steering gear or a
|| || || || || || || || || || || || || || || ||
bad power steering pump. Who is right?
|| || || || || ||
A. Tech A only
|| || ||
B. Tech B only
|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-B. Although further diagnosis will
|| || || || || || || || || || || ||
be necessary, Tech B is right. Tech A is wrong because, when there is a
|| || || || || || || || || || || || || || ||
malfunction in a variable assist power steering system, the system will allow
|| || || || || || || || || || || ||
full power steering.
|| ||
6. A customer complains that a vehicle wanders on a bumpy road and needs
|| || || || || || || || || || || || ||
continual driver correction to stay straight. What could be Wrong?
|| || || || || || || || || ||
A. Excessive negative front caster
|| || || ||
B. Insufficient front toe
|| || ||
,C. Rear or front bump steer
|| || || || ||
D. All of the above - CORRECT ANSWER✔✔-D. Excessive negative caster,
|| || || || || || || || || || ||
insufficient front toe, and front or rear bump steer could cause a vehicle to
|| || || || || || || || || || || || || ||
wander on a bumpy road.
|| || || ||
7. While aligning a front end, a technician finds the toe out on turns
|| || || || || || || || || || || || || ||
(turning Radius) to be greater than the manufacturer's Specs and it has 2.0
|| || || || || || || || || || || || ||
degrees difference from the left side to the right side. Which, if any, of the
|| || || || || || || || || || || || || || ||
following could be the cause? || || || ||
A. Nothing is wrong; the vehicle has a non symmetrical steering design.
|| || || || || || || || || || ||
B. Bent pitman arm
|| || ||
C. bent tie-rod
|| ||
D. Both B and C - CORRECT ANSWER✔✔-D. either a bent pitman arm or a
|| || || || || || || || || || || || || || ||
tie rod could cause the specifications for the toe out on turns to be out of
|| || || || || || || || || || || || || || || ||
spec. Vehilces with non symmetrical steering systems will have a difference
|| || || || || || || || || || ||
from side to side, but the difference will not exceed the manufacturer's
|| || || || || || || || || || || ||
specs and it rarely has a greater than 1.5 degrees difference from side to
|| || || || || || || || || || || || || ||
side.
8. When checking a tire, a tech find it to have too much radial (up and
|| || || || || || || || || || || || || || || ||
down) runout. Tech A says to rotate the tire and wheel assembly on the
|| || || || || || || || || || || || || ||
mounting studs to correct the problem. Tech B says to rotate the tire on the
|| || || || || || || || || || || || || ||
wheel assembly to attempt to bring the runout within specs. Who is right?
|| || || || || || || || || || || || ||
A. Tech A Only
|| || || ||
B. Tech B Only
|| || ||
C. Both A and B
|| || || ||
, C. Neither - CORRECT ANSWER✔✔-B. Rotating the tire on the wheel will
|| || || || || || || || || || || ||
compensate for wheel/tire differential (positioning the highest spot on the
|| || || || || || || || || ||
tire at the lowest spot on the wheel.) Whereas', rotating the wheel assembly
|| || || || || || || || || || || ||
on the mounting studs will have no effect on runout.
|| || || || || || || || || ||
9. If you readjust camber on the left front strut, which, if any, of these specs
|| || || || || || || || || || || || || || ||
might change
|| ||
A. Right caster
|| ||
B. Left toe and total toe
|| || || || ||
C. SAI
||
D. None of the above. - CORRECT ANSWER✔✔-B. Readjusting camber will
|| || || || || || || || || || ||
have an affect on the individual toe for the left wheel as well as the total
|| || || || || || || || || || || || || || || ||
toe. SAI is not adjustable and generally, caster is not adjustable either on a
|| || || || || || || || || || || || || ||
strut suspension.
||
10. Too much caster on the left front wheel will cause the __________
|| || || || || || || || || || || ||
A. vehicle to drift to the left
|| || || || || ||
B. Left tire to wear on the outside edge
|| || || || || || || ||
C. vehicle to drift to the right
|| || || || || ||
D. left tire to wear on the inside edge. - CORRECT ANSWER✔✔-C. A vehicle
|| || || || || || || || || || || || || ||
will tend to steer or drift to the side with the least amount of caster. Caster
|| || || || || || || || || || || || || || ||
will not cause tire wear, but excessive camber will cause wear to the inside
|| || || || || || || || || || || || || || ||
of outside shoulders of a tire.
|| || || || ||
12. A pressure test is being performed on a car with power steering. The
|| || || || || || || || || || || || || ||
pressure readings taken when the wheels are at the right and left stops are
|| || || || || || || || || || || || || ||
below specs. The tester readings are normal when the tester shutoff valve is
|| || || || || || || || || || || ||

|| || || || || || || || ||
A. Tech A only
|| || ||
B. Tech B only
|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-C. Both Techs are right. Too much
|| || || || || || || || || || || || ||
runout or static out of balance in the front wheels will cause a vibration
|| || || || || || || || || || || || || ||
3. A vehicle has front wheel shimmy at low speed and requires increased
|| || || || || || || || || || || || ||
steering effort. Tech A says that too much positive camber could be the
|| || || || || || || || || || || || ||
cause. Tech B says that too much Positive caster could be the cause. Who is
|| || || || || || || || || || || || || || ||
right?
A Tech A only
|| || ||
B. Tech B only
|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-B. Excessive positive caster will
|| || || || || || || || || || || ||
increase steering effort, cause the steering wheel to return too rapidly. cause
|| || || || || || || || || || ||
wander at high speed and shimmy at low speed.
|| || || || || || || || ||

|| || || || || || || || || || || || ||
EXCEPT:
A. Caster
||
B. Wheel balance
|| ||
C. Toe-In
||
D. Camber - CORRECT ANSWER✔✔-A. Caster that is out of spec will affect
|| || || || || || || || || || || || ||
steering and handling characteristics, but will not cause tire wear. Whereas,
|| || || || || || || || || || ||
too much toe in or out would severely wear the tires. Additionally, excessive
|| || || || || || || || || || || ||

|| || ||
C. Both A and B
|| || || ||
D. Neither A or B - CORRECT ANSWER✔✔-B. Although further diagnosis will
|| || || || || || || || || || || ||
be necessary, Tech B is right. Tech A is wrong because, when there is a
|| || || || || || || || || || || || || || ||
malfunction in a variable assist power steering system, the system will allow
|| || || || || || || || || || || ||
full power steering.

might change
|| ||
A. Right caster
|| ||
B. Left toe and total toe
|| || || || ||
C. SAI
||
D. None of the above. - CORRECT ANSWER✔✔-B. Readjusting camber will
|| || || || || || || || || || ||
have an affect on the individual toe for the left wheel as well as the total
|| || || || || || || || || || || || || || || ||
toe. SAI is not adjustable and generally, caster is not adjustable either on a
|| || || || || || || || || || || || || ||
strut suspension.
||
10. Too much caster on the left front wheel will cause the __________
|| || || || || || || || || || || ||
A. vehicle to drift to the left
|| || || || || ||
B. Left tire to wear on the outside edge
|| || || || || || || ||
C. vehicle to drift to the right
|| || || || || ||
D. left tire to wear on the inside edge. - CORRECT ANSWER✔✔-C. A vehicle
|| || || || || || || || || || || || || ||
will tend to steer or drift to the side with the least amount of caster. Caster
|| || || || || || || || || || || || || || ||
will not cause tire wear, but excessive camber will cause wear to the inside
|| || || || || || || || || || || || || || ||
of outside shoulders of a tire.
